About my design:

Many old hard disk in computers are being replaced everyday because they are too small to handle huge data or large programs such as new version of Windows programs. Now, the minimum size of hard disk is about 80 GB. So, the small sizes, such as the 800 MB, 1.2 GB or 3.5 GB, are no longer in use. When we replace hard disks in our computers, the old one cannot be of any use. So, most of them are thrown away to junk shops reducing their price to only about $1 per set.
Actually, these old hard disks still function properly, only that they have too little space for storage that are used in present days.
Looking inside the hard disks, there are many things we can experiment from. One of them is the hard disk arm which can move freely betweena pair of very strong magnets. The hard disk arm consists of small coil to produce magnetic field. When we put small amount of current into the coil, it will produce magnetic field against magnetic field from the pair of magnets. The result is amazing.
